Abstract: A blood clotting time measurement cartridge includes: an inlet on one end of a measurement flow channel and through which blood is introduced; a communication opening on the other end of the measurement flow channel and through which air suction or air pressure application or the blood introduced from the inlet is performed; a moving body arranged in the measurement flow channel moves; a clotting accelerator applied on at least one of a flow channel wall surface, which defines the measurement flow channel, and the moving body; and a detection area through which light is transmitted to a predetermined part in the measurement flow channel, and where it is possible to detect with light whether there is the moving body or the blood making a reciprocating motion in the measurement flow channel in association with air suction or air pressure application or the blood from the communication opening.

Abstract: A blood clotting time measurement cartridge that can keep an amount of blood constant while simplifying a configuration and easing a blood injection operation, and a blood clotting time measuring device using the cartridge. The cartridge includes a measurement flow channel wherein blood is housed and transmission of light detects whether there is blood in a predetermined position, an introduction opening on one end side of the channel from which blood is introduced, a communication opening on the other end through which it is possible to cause, by suction or pressurization of air or blood introduced from the introduction opening, the blood in the channel to make a reciprocating motion so as to pass through the predetermined position, a partition wall that partitions a blood injection space connected to the introduction opening, and an absorption member on an outer side of the partition wall that absorbs blood beyond the wall.

Abstract: A device has a gate portion for recovering floating materials on liquid surfaces and for following vertical movement of the liquid level. Gate floats around and rotatable about the gate portion retain the gate portion near the liquid level. Main floats outside the gate floats support a recovery portion. A blade-shaped projection on an outer circumferential part will rotate along the liquid level. A driving device rotates the gate float, with loads of the driving device being supported by the main floats.

Abstract: The present invention provides a device for recovering floating materials on the liquid surface, arranged as the gate portion for recovering floating materials on the liquid surface is installed at the recovery portion in a state of following vertical movement of the liquid level and being able to move freely in a vertical direction, and the float is composed of a plurality of gate floats which are disposed around and in the vicinity of the gate portion and which float and retain the gate portion near the liquid level, and a plurality of main floats which are disposed further outside than the gate floats to float and support the recovery portion, in which the gate floats are arranged in such a manner that they rotate around and in the vicinity of the gate portion, thereby raking and gathering floating materials to the gate portion, and the main floats are arranged in such a manner that at least a part installed with a blade-like projection is provided on an outer circumferential part will move rotationally

Abstract: A solid-liquid separator prevents wear of a self-priming liquid pump connected to a cyclone mechanism and a solid-liquid mixture can be purified at low cost. The separator separates sludge in the liquid by a cyclone in a separation portion directly or indirectly connected to a suction of the upstream side of the pump. The separation portion has a first and second cyclones with the first cyclone disposed in said second cyclone coaxially. A tank disposed under the cyclones collects separated from the liquid.

Abstract: An oil-water separator with a self-priming pump of high oil-water separation ability enables a mixed liquid to be introduced into the oil-water separator without causing emulsification. A separator portion separating a mixed liquid includes a rough cyclone separation portion. A main separation portion downstream of the rough separation portion performs main separation according to specific gravity. A water discharge portion connected to the main separation portion discharges water. An oil storage tank stores the oil separated from the water and overflowing the main separation portion. A self-priming liquid pump connected downstream of the separator portion and connected to the water discharge portion sucks the mixed liquid from an exterior to enable venting and discharging of air.

Abstract: An object of the present invention is to provide an oil-water separator with self-priming pump of high oil-water separation ability that enables a mixed liquid to be introduced into the oil-water separator without causing emulsification.

Abstract: The present invention is to provide a solid-liquid separator with self-priming pump with which wear of a self-priming liquid pump connected to a cyclone mechanism can be prevented and a solid-liquid mixture can be purified at a low cost without requiring a special arrangement (special material or special structure) for the pump.

Abstract: The present invention provides a filtration device combined with self-priming pump in which a filter replacement work is easy and safe, and removal of air inside of a pump and priming are not necessary.
